Ohio, assignors to The National Cash Register Company, Dayton, Ohio, acorporation of Maryland Filed Nov. 22, 1957, Ser. No. 698,274 1 Claim.(Cl. 133-4) This invention relates to improvements in coin-ejectingmechanism.

The invention disclosed herein comprises an improvement over themechanism shown and described in our co-pending application, Serial No.649,959, filed April 1, 1957. As illustrated therein, the mechanism isreleased for operation by controls set up in a cash register of the typedisclosed in United States Patent No. 1,865,147, issued to Bernis M.Shipley on June 28, 1932, and in United States Patent No. 2,625,322,issued to Frank B. Moser on January 13, 1953.

The principal object of the present invention is to provide acoin-ejecting mechanism which is positive in its action and one whichdoes not depend entirely on springs to actuate the ejecting mechanism.

' Another object of the invention is to provide a novel mechanism forreleasing a feeling member from engagernent with a stack of coins in achute, prior to the operation of the ejecting member.

With these and incidental objects in view, the invention includescertain novel features of construction and combinations of parts, apreferred form or embodiment of which is hereinafter described withreference to the drawings which accompany and form a part of thisspecification.

GENERAL DESCRIPTION Described in general terms, the novel meansdisclosed herein is attached to a machine of the type shown in theabove-mentioned Shipley patent, which is capable of recording items of asale, either multiple or single, and printing a sub-total thereof. Themachine is also provided with a control for entering the amount tenderedby the customer in payment for goods. The Amount Tendered key controlsthe add-subtract totalizer so that the amount tendered is subtractedfrom the balance standing therein, which provides a negative balance, orthe amount of change to be issued. Upon clearing the negative totalbalance from the machine, certain circuits are set up automatically toactuate solenoids in the changemaking mechanism, to set up a conditionfor issuing proper coins, making up the change due the customer. Thechange making and delivering operations are effective during thenegative total clearing operation. Therefore, no mental calculation onthe part of the operator is required to determine the amount of coinsdue the customer.

The machine as shown in the above-mentioned Shipley patent is providedwith a series of amount banks of Patented Sept. 27, 196i).

keys, which control the calculation of balances in a totalizer, whichtotalizer controls the operation of a switch during negativesub-totaling operations, which switches energize solenoids in thechange-ejecting mechanism in the combinations required to issue theproper number of each of the coins. It is to be understood that onesolenoid is provided for each ejecting mechanism,

Coin-ejecting mechanism The coins 156 (Fig. 1) are stacked in a chute151 corresponding to each coin supported by the coin chute member. Thecoin chute mechanism illustrated in Fig.1 is the one issuing twopennies. A coin chute member 152 extends across the entire machine, andthe chutes 151 are provided for the desired denominational coins. Forexample, one chute is provided for halfdollars, three chutes forpennies, two chutes for dimes, one chute for nickels, and one chute forquarters. The coins are ejected from the chute 151 by a coin-ejectingmember 153, which is held in engagement with a roller 154 by a spring155 and is pivoted on a stud 156, carried by a rocking arm 157, looselypivoted on a shaft 158, carried by frames 159 of the coin-ejectingmechanism. A spring 148 urges the arm 157 counter-clockwise (Fig. 1)into engagement with a stud 161i, carried by an arm 161, loose on theshaft 155. The arm 161 is provided with a stud 162, on which ispivotally mounted a latch arm 163. See also Fig. 3. A spring 164stretched between a stud 165 on the arm 161 and a stud 166 on the latcharm 163, urges the latch arm 163 counter-clockwise, as viewed in Figs. 1and 3. The upper end 167 of the latch arm 163 normally engages an arm163, pinned to the shaft 158. The shaft 158 is rocked counter-clockwise(Figs. 1, 3, and 6) during each cycling operation of the coinejectingmechanism and thereafter returns in a clockwise direction to its normalposition. The counter-clockwise and clockwise rocking movements of theshaft 158 are obtained by means of an arm 179 (Fig. 6) secured to theshaft 158, which is connected to an arm 171 by a link 172. The arm 171is pivoted on a stud 173, carried by the right-hand frame 159. The arm171 is provided with a cam slot 174, into which projects a stud 175,carried by a disk 176. A clutch member 177 (Figs. 6 and 7) is connectedto a motor in the manner well known in the art. A clutch pawl 186,pivoted on the disk 176, isurged counter-clockwise by a spring 187 toengage the clutch member 177 when released. The disk 176 is held in itshome position by a pawl 178, pivoted on a stud 179. A spring 180normally maintains the upper end of the pawl 178 in engagement with anotch 181 in the disk 176;. Secured to the arm 178 is a clutch arm 182,connected to the armature 183 of a solenoid 184. The connection may beeither by a stud, as shown in Fig. 6, or by a stud and notch, as shownin Fig. 7. A spring 185 normally maintains the clutch arm 182 inposition to maintain the clutch pawl 136 from engagement with the clutchdisk 177, and, when the solenoid 184 is energized at the proper timeduring the machine cycling of the cash register, to which the presentinvention is shown applied, the solenoid rocks the clutch arm 182counter-clockwise, to release the clutch pawl 186 to engage the clutchdisk 177. Thereafter, the clutch member 177 rotates the disk 176counter-clockwise (Figs. 6 and 7).

As the disk 176 is rotated, the stud 175 thereon, moving in the cam slot174, rocks the arm 171 to move the link 172 toward the right (Fig. 6)and rock the arm 170 counter-clockwise to thereby rock the shaft 158likewise. As the stud 175 passes 180 degrees of its rotation, the stud175, moving in the cam slot 174, returns the arm 171 to its normalposition, thus rocking the arm 170 and the shaft 158 clockwise back toits normal position.

When the shaft 158 is rocked counter-clockwise (Fig. 3), the arm 168releases the pawl 163 to rock counter clockwise under the action of thespring 164. Normally a shoulder 190 on the pawl 163 engages a stud 191on an armature 192, pivoted on a rod 193, carried between the sideframes 159. A spring 194 maintains the armature 192 in the positionshown, with a finger 195 thereon engaging a block 196.

Thus, when the stud 191 of the armature 192 lies in the path of theshoulder 190, when the arm 168 is rocked counter-clockwise (Fig. 3), thearm 163 cannot follow. However, when the relay 131 is energized, thearmature 192 is rocked counter-clockwise to withdraw the stud 191 fromthe path of the notch 190, and therefore, when the arm 168 is rockedcounter-clockwise, the arm 167 is permitted to follow until a shoulder197 thereon is moved into the path of movement of a shoulder 198, formedon the arm 168. Upon continued counter-clockwise movement of the arm168, the shoulder 193, engaging the shoulder 197, carries the arm 163,together with the arm 161, counter-clockwise around the shaft 158. Asthe arm 161 rocks counter-clockwise, the arm 157, held in engagementwith the stud 160 on the arm 161, rocks the arm 157, together with theejector member 153, therewith, to eject the coins 150 from the chute anddrop them into the delivery spout 200.

In order to arrest operation of the machine when no coins are left inthe chute 151, a switch (not shown herein but fully illustrated in theabove-mentioned application) is provided to break the circuit in themotor-operating circuits. This switch is controlled by a feeler 245,engaging the stack of coins 150 under the tension of the spring 155. Theupper end of the finger 245 is provided with a projection 246, whichengages a yoke 248, pivoted on a rod 247. The yoke 248 is provided witha finger (not shown) for actuating the switch when the yoke 248 isrocked clockwise.

In order to place a minimum load on the coins 150, so that they will befree to drop in the chute 151, means is provided for withdrawing thefeeler 245 from engagement with the coins at the beginning of eachcycling operation of the coin ejector. To accomplish this, an arm 250,having a flange 251, is provided, which flange lies in the path ofmovement of the yoke 248. Secured to the arm 250 is a pitman 252, thelower end being bifurcated at 253 (see also Fig. 2) to straddle theshaft 158. The pitman 252 is provided with a cam surface 254, which isengaged by a stud 25S, carried by an arm 256, secured to the shaft 158.

Thus, when the shaft 158 rocks counter-clockwise (Figs. 1 and 2), thestud 255, engaging the cam edge 254, raises the pitman 252 to bring theflange 251 into engagement with the yoke 248, which, through itsengagement with the projection 246, rocks the feeler 245counterclockwise to withdraw the lower end of the feeler 245 fromengagement with the stack of coins 150. The cam edge 254 is so developedthat the pitman 252 is raised immediately after the arm 256 begins torock, so that the pressure on the stack of coins will be relieved atonceand will remain relieved until the very end of the machineoperation, at which time the stud 255 again engages the recessed portionof the cam edge 254, to permit the pitman 252 to drop and withdraw theflange 251 from engagement with the yoke 248 and permit the spring 155to again move the finger 245 into engagement with the stack of coins150.

The lower end of the cam arm 171 (Fig. 6) is provided with a flange 260,which coacts with a switch 261, carried on a bracket 262, supported onthe base of the machine. The switch 261 controlscertain circuits in themachine for controlling the time, during the machine operation, in whichthe relays 131 are energized. Since this part of the structure does notform a part of the novel mechanism, it is not further described,inasmuch as it is a part of the control circuits of the cash register towhich the present invention is applied.

' The mechanism for closing the switch 260, shown in Fig. 6,issatisfactory for operation in certain machines. However, in other cashregisters to which the invention is attached, a quicker-acting switchmechanism is required. Such a mechanism is disclosed in the modifiedform illustrated in Fig. 7.

In the modified form of the mechanism, the arm 171 is cut short at itslower end, to leave 011 the switchoperating flange 260. Aseparately-operating arm 265 is pivoted on stud 173, adjacent the arm171. The arm 265 is provided with the switch-operating flange 260. Thearm 265 is provided with a stud 266, which is normally held inengagement with a notch 267 on the free end of a spring-actuated latcharm 268, pivoted on the stud 179. A spring 269, stretched between thestud 266 and a stud 270 of the latch arm 268, maintains the stud 266 ofarm 265 in the notch 267. The stud 266, engaging an extension 271,limits clockwise movement of the latch arm 268. The latch arm 268engages a stud 272 on the clutch arm 182.

When the solenoid 184 is energized, and the clutch arm 182 is rockedthereby to release the clutch pawl 186, the stud 272 rocks the latch arm268 counter-clockwise to lower the notch 267 and permit the spring 269to rock the arm 265 until the stud thereon engages a notch 273 in theend of the latch 268. At the end of the rotation of the disk 176, thestud 175 thereon restores the arm 265 to normal position and permits thelatch arm 268 to be restored to normal position. The stud 175 is notchedat 274 to provide a clearance for the arm 265 when released by latch arm268. A cut-back 275 in the arm 265 provides clearance to allow the arm265 to move when released by latch arm 268.

Thus it is clear that the switches 261 are actuated at the instant themachine is released. In the form shown in Fig. 6, the switches 261 areactuated by the stud 175 after a partial rotation of the disk 176.

While the forms of the invention disclosed herein are admirably adaptedto fulfill the objects primarily stated, it is to be understood that itis not intended to confine the invention to the forms or emhodimensdisclosed herein, for it is susceptible of embodiment in various otherforms.
